'Carella, 35572 Strathcona, Mount Clemens, Mich. 48043 Filed Aug. 7, 1967, Ser. No. 658,774 Claims. (Cl. 3346) ABSTRACT OF THE DISCLOSURE An archery bow sight assembly including a bracket adapted for attachment to an archery bow and having two spaced vertical slots with a plurality of individual circular sights disposed adjacent the bracket and attached thereto by support shafts which extend through the slots.

It is old to utilize a sight assembly in combination with an archery bow so that the target may be viewed through the sight to position the bow properly to provide the proper trajectory of the arrow whereby it will reach the target. In one prior art assembly, a bracket is adapted to be attached to an archery bow and has a sighting ring attached thereto so that it may be adjusted vertically. The problem with such a device is that it does not tell the archer the range to target and is not well suited for quick sighting which is necessary in a hunting situation. For example, an individual hunting deer must be able to rapid-1y sight and release the arrow toward the target which is the deer. In such a prior art assembly, the sight must be adjusted relative to the bracket for each different distance from the target whether it be known or guessed.

In another prior art assembly, a plate-like member is adjustably secured to the archery bow and includes a plurality of open-ended vertically-spaced gauge-actingsighting slots. The vertical distance presented by each sighting slot is difierent than that presented by all of the other sighting slots and the vertical distance presented by each slot coincides with the apparent vertical height of a particular target when viewed through the slot at a particular distance. For example, the average deer has approximately twelve inches of vertical height in the chest area, which is the target. This twelve inches of vertical distance has a different apparent vertical height at different distances from the deer. In using the aforementioned prior art sight, the apparent vertical height of the deer is matched to a particular slot in the sight so that the archery bow is in the position to give the arrow the trajectory for reaching the target. The problem with such a sight is that the relative positions between the different sighting slots cannot be changed to compensate for various bow characteristics and different operators of the bow. Furthermore, in some instances, the apparent height of a given target at one distance will overlap with the apparent height of the target at a different distance and obviously the slots in such a plate device cannot overlap. In addition, a special adjustment plate is required to compensate for different operators and bow characteristics. This means that the hunter would sight through the fixed slots to find correct range. Then he would have to adjust the fixed slots to precalibrated marks on the adjustment plate to give his arrow its correct position. This means a hunter would have to adjust his fixed slots each time he saw a deer at a different distance.

Accordingly, an object and feature of the instant invention is that once calibrated, it requires no adjustment, range finding, or computing while hunting and nothing more is required than for the hunter to match the correct circle to the deers apparent vertical height and shoot.

Accordingly, it is an object and feature of this invention to provide an improved sight assembly adapted to be attached to an archery bow including a plurality of "ice individual sights which may be calibrated and positioned relative to one another to compensate for the various characteristics of a given archery bow and the operator and which may be repositioned in the event the bow characteristics or operator change.

Another object and feature of this invention is to provide an improved sight adapted for attachment to an archery bow and including a support means with a plurality of independent sights respectively connected to the support means with each of the sights defining a vertical distance different than the vertical distance defined by the other sights so that each sight may be independently positioned relative to the support means for properly aiming the bow by moving the bow to view a target at a distance from the bow through the respective sights until the apparent vertical height of the target equals the vertical distance defined by one of the sights, thereby to properly aim the bow for the particular target.

Other objects and attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIGURE 1 is a fragmentary perspective view of the bow sight assembly of the instant invention in combination with a bow and illustrating an arrow;

FIGURE 2 is an enlarged fragmentary elevational view of the sight assembly of the instant invention attached to an archery bow; and

FIGURE 3 is a fragmentary view taken substantially along line 33 of FIGURE 2.

Referring now to the drawings, a bow sight assembly is generally shown at 10 in combination with an archery how 12. The bow sight assembly includes the support means comprising the bracket 14 and a plurality of independent sights 18. The bracket 14 is attached to the archery bow by the screws 16. The independent sights 18 are respectively connected to the bracket 14. The bracket 14 includes a flange 20 having a pair of spaced vertical slots 22 disposed therein. Each sight includes a support shaft 24 which extends through one of the slots 22 and adjustment means comprising threads on each support shaft 24 and a pair of nuts 26 threaded thereonto and clampingly engaging opposite sides of the flange 20. The nuts 26 allow the adjustment of the vertical position of each support shaft 24 relative to the bracket 14 and archery bow 12. The sights 18 are, therefore, attached to the bracket 14 in a plurality of spaced vertical rows as best illustrated in FIGURE 2.

Each sight 18 defines a vertical distance, as illustrated by the distance X for the sight 18'. The vertical distance defined by each sight is different than the vertical distance defined by the other sights and each sight 18 may be independently positioned relative to the bracket 14 for properly aiming the how by moving the bow to View a target at a distance from the bow through the respective sights until the apparent vertical height of the target equals the vertical distance defined by one of the sights 18. More specifically, the individual sights 18 are positioned vertically relative to one another and relative to the bow 12 depending upon the various characteristics of the bow and the operator so that when the target is viewed through the proper sight, the bow will be positioned to compensate for the distance from the target so that the arrow will follow a trajectory to hit the target.

The means defining the vertical distance for each sight presents an aperture having an endless periphery and, more specifically, is a circular ring, the circular rings of the various different sights having different diameters. As illustrated in FIGURE 3, various of the individual sights 18 are disposed in overlapping relationship. As alluded to above, this is a very important advantage of the instant invention.

Once the sight assembly has been calibrated so that the individual sights 18 are in the proper position, the operator will view the target through the sights until the apparent height of the target matches the vertical distance defined by one of the respective sights 18, see FIGURE 3. Once in this position, the bow will be in the correct position to compensate for the distance from the target so that the arrow will follow the proper trajectory to reach the target.

Thus. the sight assembly of the instant invention has versatility in calibration not afforded by the prior art assemblies in that the respective individual sights may be positioned relative to one another to compensate for the various characteristics of the archery bow as well as the operator so that once calibrated, no further positioning is needed and a target may be very rapidly sighted.

The invention has been described in an illustrative manner and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.

Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
